The beginning of the work process is that the box feeds the labeling machine at a constant speed on the conveyor belt. The mechanical fixing means separate the boxes a fixed distance apart and push the box in the direction of the conveyor. The mechanical system of the labeling machine comprises a driving wheel,
A labeling wheel, and a reel. The drive wheel intermittently pulls the label tape and the label tape is pulled out of the reel while the label wheel is pressed against the box through the labeling wheel. Open-loop displacement control is used on the spool to maintain the tension of the label tape. Since the labels are closely attached to each other on the label tape, the label tape must be continuously stopped and stopped.
The label is affixed to the case with the labeling wheel moving at the same speed as the case. When the conveyor reaches a certain position, the label drive wheel will accelerate to match the speed of the conveyor belt, after labeling, and then decelerated to stop.
Since the label may have sliding, so it has a registration mark above, to ensure that each label is correctly placed. The registration mark is read by a sensor. During the belt deceleration phase, the drive wheel will readjust its position to correct any position error on the label tape.
